Figure 2.

Relative variable importance plots for caries risk assessment (CRA) items. Horizontal axis represents mean decrease in accuracy (variable importance) from random forests models for (A) baseline CRA items and practitioners’ caries risk designation, (B) baseline CRA items and baseline caries presence, (C) baseline CRA items and follow-up caries presence, and (D) change in CRA items from baseline to follow-up and follow-up caries presence. Filled plotting symbols indicate P < 0.05. Note: interrupted scale for panels A, C, and D.
